Answer:
48.5654 degrees to the nearest ten thousandth.
Step-by-step explanation:
We can use the cosine rule to do this
First find m < C:
45^2 = 34^3 + 34^2 - 2.34.34 cos C
Cos C = [45^2 - (34^3 + 34^2 )] / (-2312)
= -287 / -2312
= 0.1241349
m < C = 82.8692 degrees
Therefore m < B = 180 - 82.8692) / 2 (as ABC is an isosceles triangle).
= 48.5654 degrees
Step-by-step explanation:
1. if to evaluate the given experssion, then
7⁶(7²-7+1)=7⁶*43.
2. if to divide this evaluated expression by 43, then
7⁶*43/43=7⁶.
Answer:
120%
Step-by-step explanation:
The ratio you are solving is 48/40
Divide the numerator by the denominator just like you would do with any other fraction.
48÷40=1.2
Your answer is 120%
Answer:
The length is 73 m, and the width is 59 m.
Step-by-step explanation:
perimeter = 2 * length + 2 * width
Let the width = w
length = w + 14
width = w
perimeter = 2 * (w + 14) + 2 * w
perimeter = 2w + 28 + 2w
perimeter = 4w + 28
perimeter = 264
4w + 28 = 264
4w = 236
w = 59
length = w + 14 = 59 + 14 = 73
Answer: The length is 73 m, and the width is 59 m.
105-32=73
73/105=.695
.696 x 100 = 69.5%
